Question

You are making a colorful cake for a birthday party and need to use 3

3
drops of food coloring for every 7
7
ounces of icing. How many drops of food coloring do you need if you are using 28
28
ounces of icing?

Answer 1

To determine how many drops of food coloring you need for 28 ounces of icing, you can set up a proportion based on the given ratio:

3 drops of food coloring / 7 ounces of icing = x drops of food coloring / 28 ounces of icing

Now, you can solve for x:

3/7 = x/28

To isolate x, cross-multiply and then divide:

3 * 28 = 7 * x

84 = 7x

Now, divide both sides by 7:

x = 84 / 7
x = 12

So, you would need 12 drops of food coloring for 28 ounces of icing.
